The original 300depicted the historic Battle of Thermopylae (albeit taking some fairly liberal factual liberties) and in doing so, made a huge star out of Gerard Butler and director Zack Snyder, helped resurrect the Swords and Sandals genre (along with the Oscar-winning Gladiator) and showed how a movie made nearly entirely of CGI could be not only technologically possible but economically viable as well.

While Snyder is around for this sequel as a producer and writer only, this tells more or less a parallel story of the Athenian general Themistocles who was victorious at the Battle of Marathon at which the Persian emperor Darius (Naor) was killed by an arrow fired by Themistocles himself. His son and heir, Xerxes (Santoro) was manipulated by his most talented and vicious general Artemesia (Green) – who is of herself Greek descent – into ascending into a role as God-Emperor, which apparently makes you ten feet tall in the process.

While Xerxes is attacking King Leonidas (Butler, in flashback) at Thermopylae, Artemesia has engaged a small and ragtag Greek fleet made up mainly of fast, maneuverable Athenian ships along with a few motley vessels supplied by the other city-states of Greece who despite the peril represented by the vast army of the Persian empire are suspicious and quarrelsome among themselves. While Themistocles has some success at sea, the wily Artemesia lures his fleet into a trap and decimates it, leaving it with a handful of ships. As Xerxes gloats over his defeat of Leonidas and his burning of Athens, Artemesia brings her fleet in to finish off the Greeks once and for all – and after failing to move the grieving Queen Gorgo (Headey) of Sparta to help her fellow Greeks, Themistocles knows that Artemesia might well do just that.

This is made in the same style as the original 300 with lots of green screen, lots of digital effects, plenty of CGI blood splatters, bare-chested Spartans with six-pack abs and enough testosterone flowing to drown Australia. It’s the kind of movie that is meant to make it’s young male gamer/fanboy target audience beat their chests and grunt, a knuckle-dragging epic in which the only major female character has a bare-breasted wild sex scene with her supposed enemy that was more violent than sexy but less violent than it was improbable (yes Lena Headey is also in the movie but only for a few scenes).

What differentiates this from 300 is that for all its macho posturing, the original film had at least some semblance of humanity, actual characters who the audience could latch onto and even care about. Here, mostly the players are cannon fodder, hurled into a meat grinder of sharp blades, battle axes, spears, flaming arrows and sinking ships, gobbets of flesh dripping gore arcing in a graceful parabola through the air after being carved from shrieking soldiers. I can’t deny that there is a certain gratification in it, a primitive caveman reaction that is both visceral and appalling, but it must be dutifully cataloged if one is to be honest.

While the dialogue tends more towards jingoism, I also will be the first to admit that the visuals are impressive. You’d swear that you were watching titanic battles being fought in rolling storm-driven seas but the reality was that the actors had not a drop of real water on them – the ocean and the ships are all CGI. About the only thing that wasn’t CGI in the movie was Eva Green’s breasts and I have my doubts about those too.

Green does acquit herself the best and that is the only kindness I can spare the acting which is for the most part over-the-top and melodramatic. Green seems to be having a good time as a badass and it shows. She utters the most cringe-worthy dialogue with a straight face and her smiles drip venom as you would expect from an excellent villain. Stapleton doesn’t have the charisma that Butler has, at least not yet. His Themistocles did a lot of shouting but didn’t really inspire me to want to follow him into battle so his abilities as a leader of men were sharply called into question at least from my vantage point.

I have to mark this down as one of the year’s first disappointments – every year provides several such in the movie calendar. Unfortunately, Snyder was a bit too busy resurrecting the Superman franchise to put in the time and effort to direct this and while his hand is evident in the production end, certainly this didn’t have the wow factor that would make me want to see the third movie in the franchise (one is reportedly in the pipeline should the box office warrant it). In the end, this is a feast for the eyes but does little for the soul beyond providing some instantly forgettable entertainment.

REASONS TO GO: Impressive CGI.

REASONS TO STAY: Lacks a Gerard Butler to keep the audience’s attention. A little too mannered and over-the-top. Hardly any human element to the story.

FAMILY VALUES: If the fake blood hadn’t been CGI there would have been enough to fill one of the Great Lakes with it. There’s also a ton of hack/slash violence, a good bit of nudity and sexuality, and a bit of foul language.

TRIVIAL PURSUIT: While the titles say that the film is based on Frank Miller’s graphic novel series Xerxes, the screenplay was written concurrently with the graphic novel which has yet to be published and has said to have changed massively since the film was made.
